A computer-based wristwatch that provides an extension to a smartphone via Bluetooth. Emerging in 2011, by 2015 there were more than 100 models on the market. A major smartphone advantage is handling phone calls and messages without having to extract the phone from pocket or purse, although not every model supports this feature. The Gear S was the first stand-alone smartwatch to have a unique phone number and make calls entirely on its own (see Samsung Gear S).

Smartwatches often include exercise apps for managing health (see fitness tracker) and may have built-in pulse sensors for reading the wearer's heartbeat. After only a few years in the market, fitness turned out to be a major inducement for a smartwatch. Where applicable, mobile apps are enhanced to synchronize with smartwatches.

In 2015, the introduction of the Apple Watch line made quite a splash as both a fashion statement and a smartwatch with unique features (see Apple Watch).
